Fatigue Performance of Open Drilled Holes with Burrs



Center hole tension specimens with similar shapes but different sizes were tested under constant and variable amplitude loads. Fatigue degradation due to burrs was found to be small and/or negligible for relatively large holes with diameters such as 10 and 5 mm, but was marked for smaller holes with diameters of 2 and 1 mm. Finite-element analysis shows that peak stress at a semicircular arc-shaped burr increases as the hole becomes smaller, if the same thickness and the same heights of the burrs are assumed. It is indicated that careful deburring is particularly necessary for small holes to prevent fatigue degradation.
